VAPOR-BURN ER.

SPECIFICATION forming part of Letters Patent No. 398,689, dated February 26, 1889. Application filed April 6, 1888. Serial No. 269,846. (No modeld To all whom it may concern.-

Be it known that I, GEORGE W. BILLINGS,

of Cleveland, county of Ouyahoga and State 1 of Ohio, have invented new and useful Improvements in Vapor-Burners; and I do hereby declare that the following is a full, true, and exact description thereof.

My invention consists in the means employed for supplying two or more burners with vapor from the vapor-generator controlled by a single needle-valve mechanism and an intermediate commingling-chamber provided with separate and controllable con duits leading to the combustion-chamber of every burner arranged. in connection with one and the same stove-frame.

The essential and most important part of my invention is the application of a mixing or commingling chamber, into which, by means of a comparatively long tube, vapor from the orifice of a needle-valve is directed to enter under pressure of the gasoline in the reservoir. The current which is thus created within and by said long tube causes a large volume of air to be drawn in by the vapor and to thoroughly mix with the same within said chamber. This aerated. vapor or gas has the property of being pract ically non-condens- 1 able and of being conveyable in that condition to the various burners arranged in connection with the stove. This gas or mixture of vapor and air is distributedto the various of the needle valve F.

burners, and by the peculiar arrangement of the openings in the mixing-chamber the frictional resistance of the said gas is reduced to a minimum in its passage through the pipes. As above stated, the tubes or conduits leading from the mixing or com mingling chamber are controllabletl1at is, they are provided with cut-off 'alvcs, which allow when opened the vapor to pass unobstructed through said tubes to the burners, thus avoiding friction and waste in vapor to a marked extent. Furi thermore, there another advantagein the i arrangement of the single needle-valve by which the escape of gasoline from the reservoir is prevented. 13y my arrangement there is but one orifice through which. gasoline can ever pass, and. that orifice controlled by a single needle-valve, the closing of which absolutely prevents all escape of gasoline.

understand the nature of this invention, ret' crence will be had to the following specification and annexed drawings, making part of the same.

Figure 1. represents partly a plan view and partly a horizontal section of a compound vapor-burner provided with the improve ments above referred to. Fig. 2 is a vertical section of the center burner on line at. Fig. 3 is a side elevation of the same, and Fig. at is a partial front view of Fig. 1. Fig. 5 represents the inner face view of one-half of a cut-off valve used in connection with the mechanism above referred to. Fig. 6 illustrates aperspective view of a spring or tension plate used in connection with said gatevalve.

Like letters of reference refer to like parts in the drawings and specification.

In the drawings, A represents the stand or feed-pipe shown in Figs. 1 and 3, which is at-- tached to the center or primary burner, B, to convey the gasoline from the reservoir, with which said pipe is connected, to the vaporgenerators C D, which are arranged on the exterior wall of the combust-ion-chamber ot' the center burner, B. In the chambers O D the gasoline is generated into vapor by the action of the heat from the center burner. The pipe E is in open relation with said chambers OD and leads the vapor to the orifice On opening the valve F the vapor escapes into the tube G. Said needle-valve F is of the usual construction, as seen in Figs. 1 and 2; also the generators O D, which form, with the pipe E and burners B, an entirety.

The tube G, above referred to, is funnelshaped at the front end thereof, and the rear end is connected and in open relation with the case II, the interior of which serves as a commingling-chambcr for the vapor and air, the latter being drawn in by the force under which the vapor enters the tube G, and the funnel-shaped end of the tube G- is for the purpose of increasing the current of airthat is, capacity 01. the tube G.

Owing to the comparatively large diameter and great length of the tube G enough air is given ample space to follow the inflowing vapor and mix or c'onimingle with the same within the case H. The result is that both the air and vapor unite and form apractically noncondensable combustible gas.

From the case H or commingling chamber are leading, respectively, the tubes I, J, K, and L, Figs. 1 and 3, to the various burners, which are arranged in connection with one and the same stove-frame. Each of said tubes is provided with a cut-off valve, as seen at M M' M Mi, so that one or all at the same time may be in open relation with the coinmingling-chamber and furnish vapor for the combustion-cha-mber of the respective burn= er with which they are connected. The cut-off M is arranged in relation to and with the pipe I. By said slide M the opening a on top of the case II is controlled, and the flanges b of the pipe I guide and retain said slide over the opening a. A similar opening, a, is also in the slide M, so that on drawing said slide in direction of the arrow the position of the opening a may be moved, whereby it may partially register with the opening a, or be in line therewith, so as to allow of a full and free flow of gas from the case II to the com bustion-chamber of the burner B. As shown in Fig. l, the opening a is entirely covered by the slide M, and no communication is had between the tube I and the case II." Theheat developed from the burner B can be so controlled by the described means that when only one fire is used a marked saving of gasoline is the result. By this arrangementthe burner B is or can be used for cooking purposes by generating vapor for its own use only as well as for that of'the others connected therewith, as set forth. The'tubes J and K lead the'va'porfrom the case H to the eo1nbustion chamber of the side burners,as indicated in Fig. 1, wherein a part of one of said side burners is shown in connection with the tube K. Through the tube L is conveyed the Supply of vapor" Itoa burner generally irranged in conneetion'with an o ""n located lo'wthe't'op of the stove." 'Subslt ntia yea cut-off valves used in connection" with the tubes}, K, and L are all alike. The tubes'J and K, however, require the branches of said valves to run in an angular direction with the slide thereof, owing to the angular'direction in whichthe pipes J and K ext end "to their re? spective'burners. Fig. 5,"for instance, illustrates the inner face view of the side plate, (Lot valve-casingM, wherein the slide e is fitted into the recess 61-, and into the recess (Z? is inserted the tension-plate f. By this means the slide e is slightly pressed against the plain face of the adjoining side plate of the valve-casing M, as seen in Figs. 1 and 2. The side plates of an the casings cut-olt' valves are connected by meansof the screw bolts z, and the valves are connected with the pipes by means of the set-screws j. (See Figs. an 3 v a In the drawings the recess (1 is shown as formed by means of the liner is, which is inlaid betweenthe side plates of the valve and cut out, so as to enable the operation of the slide 6. The pressure with which the plate f bears against the slide 6 causes the slide to remain in whatever position it may be set in adjusting the fires. The slides c are operated by means of the rods N, which are 'connccted with said slides, as seen at Z, Figs. 1 and 3, the free ends thereof extending out in a direction to be of easy access for the operator.

The valve M Fig. 1, is shown closed, whereas the valve M, Fig. 2, is drawn open. The pin on, which is secured to the inner end of the slides, prevents the same from being drawn back farther than necessary to attain an unobstructed passage through said valve. The hole in the plates If is of a corresponding diameter with the bore of the valve for the same reason.

The above-described compound burner is operated in the following manner, viz: First of all, all valves are closed, and the'drip eup O, which is attached to the tube G, is supplied with gasoline and ignited to heat the pipe E and the generators C and I). As soon as sufficient vaporis generated, then the valve F'i's opened and the vapor escapes into the mixing-chainber. On withdrawing the slide M the vapor will return in the tube I to the center burner, B, which burner is then ignited to continue the generation of vapor, not only for its own use, but also for that of all the other burners connected therewith, and which can be started on opening the respective cut-off valves. By the center burner, B, vapor is generated for all the burners; hence the same must be kept in operation as long as any one of the others shall burn. If, for instance, the stove has been in full operationthat is, the needle-valve F and all intermediate valves are wide open-and it is desired to extinguish the flame of the lower burner, the force of the remaining burners is then regulated directly by the needle alve F.

interposed between the outlet at of the case Hand'the valve M at the elbow of the pipe I 'is'a diaphragm of wire-gauze, n, the purpose of whicliis to preventthe explosion ofva ponwhich'wonldbe the result if the vapor should accidentally be ignited. The wirezenwill' allow'the vapor to pass through the same; but'liames of burning vapor will not extend beyond the gauze. A hat I claim, an d desire to secure by Letters Patent, is
